Review By Jerry Hillburn

In March of 2021 I reached out to the Cepheid Observatory team (V.K.Agnihotri, B. Kumar, S. Mahawar, K.Vora) requesting an imaging run on asteroid Apophis. I was impressed by their effort to obtain that data, which I will use in teaching a class on Asteroid studies.

The follow on lightcurve study they performed on the data is quite interesting and is indicative of the scientific rigor of their work


Asteroid research is conducted by a small community of highly dedicated astronomers. I for one greatly appreciate the opportunity to work together with my fellow researchers on the other side of our pale blue dot. I am only just beginning my collaboration with this team of bright thinkers, and look forward to working with them in the future! Please accept my thanks for your assistance!

“I must say, Cepheid Observatory is one of the upcoming observatories to rock the world. The detailed information provided in the website enhances the zeal in me to learn more about Astronomy. The explained procedures of astronomical astrometry, photometry and spectroscopy , develops a sense of scientific revolution in the youth. Hoping for the best times with Cepheid Observatory.

“Thank you “

Khushi Arora (India) She is currently doing graduation in science and want to be an astrophysicist and start an experimental laboratory of astrochemistry in India. She is an amateur astronomer and a motivational speaker . She is working as a citizen scientist and space educator.

“I had the great pleasure to work with Vikrant from Cepheid observatory India on the measurement of the parallax of the comet 46P/Wirtanen some time ago. He is a very kind person and he agreed to help us with our task right away. The data he contributed were very precise and so the result turned out accurately, too. Since then, I follow the activities of the Cepheid observatory group on their website and am always very impressed by their high versatility and their diligence. Keep it up, Vikrant & friends!”

Christof Wiedemair (Italy) teaches maths and physics at the “Nikolaus Cusanus” high school in Bruneck, South Tyrol, Italy. With a group of enthusiastic students he carried out a lot of astronomical observations and projects during the last twelve years with great success, thus winning also several international competitions.

Review By Georgios Lekkas

The website is very good! Very detailed information about the observations that contribute to science such as astronomical astrometry, photometry and spectroscopy. All the equipment and software used are written so it is very useful for other astronomers to compare observations and data. Keep up your amazing work!!.

Georgios Lekkas (Greece) is undergraduate student at Physics Department at University of Ioannina (UOI). He is active in sunspot observations at AAVSO and SILSO. He images planetary systems at Planetary Virtual Observatory and Laboratory (PVOL), and recently joined as active member of the “Exoclock Project” affiliated with “Ariel Space Mission”.
